Hi. I live in the Zona Norte in Costa Rica. Two nights ago, I found a huge green caterpillar crawling in our yard. It was 4-5 inches long and about 2.5 inches in diameter. It didn’t appear to have any hair or spines, or, if it did, they were very short. It also appeared to have narrow, yellow bands. The underside was black, I think. It rather looked like the caterpillar in Alice in Wonderland. In the picture, it’s next to a full size Maglite to give perspective. It made a cocoon the next day. Any help you can provide would be much appreciated.

Hi Lacey,
While we are unable to provide you with an exact species, we can tell you that this is a Giant Silkmoth Caterpillar in the family Saturniidae.
  Adult Giant Silkmoths are often large and spectacular looking.

What kind of spider is this?

Dear Curious creeper,
Several time in recent month, we have tentatively identified large Wolf Spiders as Carolina Wolf Spiders,
Hogna carolinensis, but in your case we are nearly certain that the image you submitted is of a Carolina Wolf Spider, which according to BugGuide can be identified because of:  “Orange paturons (chelicera) and black around the the “knees” ventrally are characteristics of the species.(Jeff Hollenbeck)” and both of those characteristics are evident in your image.  Carolina Wolf Spiders range well beyond the Carolinas.  Though a large individual might bite if carelessly handled, Carolina Wolf Spiders are not considered dangerous.

Dear initials,
This is a Silverfish, and it is a common household pest that is often found in damp, dark locations.

I Found this spider on a web behind my house. What the heck is it? It looks dangerous!

Dear KimH,
This Golden Silk Spider,
Nephila clavipes, is sometimes called a Banana Spider.  As you have indicated, they are large spiders, and though they might bite a person if carelessly handled, they are not considered dangerous.  Like most spiders, they do have venom, but the venom will only have a very localized reaction similar to a bee sting.  Golden Silk Spiders are known for spinning an extremely strong silk to construct their webs, and the silk has a golden color.  The strength of the silk enables them to snare large winded prey.  Golden Silk Spiders are also known for their extreme sexual dimorphism.  Your individual is a female, and she is about fifty times the size of her diminutive mate.

Hoping you’ll ID this gorgeous grasshopper I saw near Sedona, AZ, at Crescent Moon Ranch picnic area, in early Oct 2014.

Dear Curious Ellen,
Your individual looks similar to this Rainbow Grasshopper,
Dactylotum bicolor, that is posted to BugGuide, but we are not fully convinced that is a correct identification.
